I am now making dryer balls

After watching my electric bill sky rocket because of all the laundry I am doing I decided to look into dryer balls. I had heard they could cut your drying time in half which would save me a ton of money on my bill. I currently have two in my dryer and I have noticed a slight difference in my drying time but today I made a bunch more and I will be adding them to the dryer! They recommend having 8 for a large load of clothes so that is what I am going to do! Anything to save some cash!!
